Jane Goodall – what a life…

Recently, Jane Goodall passed away. Below is part of a speech she gave in 2024, and includes her ‘call’ of two kinds. First is for humans to collaborate and address problems faced by humanity, and the second is in a language understood by chimpanzees, which connects her to them. Philosophically, it summarizes her methods. What a life…

Floral colours, CV Raman and illustrations

In the 1960s, C. V. Raman wrote a series of papers on floral colors and the physiology of vision. In there, he was very interested in the origin of colors from various different flowers. This was also motivated by his fascination with optics and natural colors in vegetation. Specifically, during that era, he had a large garden at his institution and he was deeply immersed in understanding the origin of the colors from these wonderful living creatures. 

By using his knowledge of spectroscopy and the chemistry of pigments, he was able to explore some of the spectral features of the floral colors. The diagrams that you are seeing are illustrations from his paper published in 1963.

As you can observe, these illustrations are beautifully created. I don’t know whether Raman himself drew these pictures, but one should really appreciate the artist who has created them.

In a broader sense, it also indicates two important aspects. The first is that Raman was deeply motivated by natural phenomena. His intuition of optics helped him to understand the origins of a variety of natural optical processes. Spectroscopy was a crucial element in all the things that he did. The second aspect is that, in a deeper sense, aesthetics is interwoven with the pursuit of science and Raman’s work, especially towards the later part of his life, showcased it. 

There is a fascinating video conversation with Richard Feynman where he describes the appreciation of the beauty of flowers by a scientist. Raman’s appreciation of beauty is close to what Feynman is describing in the video.

C. V. Raman was a curious person. He had a deep inclination to explore natural phenomena, using the knowledge and tools he had accumulated over several decades. In that sense, he was a scientist driven by curiosity before and after his Nobel prize.

Next time when you see a flower, remember that it is a creature of beauty and science merged together.

Writing in the age of AI

A contemporary question of interest: How can artificial intelligence (AI) influence writing?

Writing has two consequences – 1) a writer processing information and communicating it to an audience; 2) a reader processing the author’s information.

The first part has an element of personal touch, just like any art or craft (for example, pottery). One does write (or create a pot) partly because it gives some pleasure and helps one to understand something in the process. There is a gain of knowledge in writing. This pleasure and wisdom through writing cannot be replaced by an external agency like AI. This is because external tools like AI are assistants of thought, not internal replacements of thought. In that sense, no external tool can replace any amateur activity because something is done for the sake of the process. Writing as a tool of self-reflection cannot be replaced by something external.

So, where is the threat? Actually, it is professional writing which is under partial threat from AI. Wherever the end product is more important than the process of writing, AI can gain prominence, provided it is accurate. It is still a partial threat because a professional writer can create questions and combinations that may arise out of individual experiences. Those lived experiences are derived from “life“, and AI cannot be a substitute for such an internal experience.

Writing, like many human endeavors, is both internal and external. The former makes us human, and that is hard to replace. After all, the A in AI stands for artificial.
